Thank you. I apologise for not asking you for verification sooner. My downvote is revoked and I've upvoted your post.

I learnt that I should have asked for verification sooner, either immediately, or as soon as you informed me you had reasons for wishing to keep said verification private. I also learnt that I should assign a higher initial probability to claims made by LessWrong members I don't know, which is a lesson I'm very glad to have learnt, since I do enjoy trusting people.
